Qubit reset beyond the Born-Markov approximation: optimal driving to overcome polaron formation
Carlos Ortega-Taberner, Eoin O'Neill, Paul Eastham
Qubits are typically reset into a known state by coupling them to a low-temperature environment. When treated in the Born-Markov approximation such couplings produce exponential re…
Quantum control of the environment in open quantum systems enables rapid qubit reset
Carlos Ortega-Taberner, Eoin O'Neill, Paul Eastham
Qubit reset is crucial in quantum technology and is typically achieved by coupling the qubit to a dissipative environment. However, the achievable speed and fidelity are limited by…
Unifying methods for optimal control in non-Markovian quantum systems via process tensors
Carlos Ortega-Taberner, Eoin O'Neill, Eoin Butler +2
The large dimensionality of environments is the limiting factor in applying optimal control to open quantum systems beyond Markovian approximations. Multiple methods exist to simul…
OQuPy: A Python package to efficiently simulate non-Markovian open quantum systems with process tensors
Gerald E. Fux, Piper Fowler-Wright, Joel Beckles +11
Non-Markovian dynamics arising from the strong coupling of a system to a structured environment is essential in many applications of quantum mechanics and emerging technologies. De…
